Vortex Optics RS-85REA Razor HD Reticle Eyepiece Ranging (MOA) Reticle

Used in conjunction with the latest generation Razor HD 27-60x85mm spotter. It's essentially like having a ruler in your spotting scope -which comes in quite handy. Just like many of our riflescopes, the eyepiece is available in both MOA and MRAD configurations to match the reticle subtension markings and turret graduations in your riflescope.
The brand-new Razor HD Reticle Eyepiece for the 85mm Razor HD Spotting Scope just made calling shots and communicating with your spotter a whole lot easier. This eyepiece is specifically designed for use with the latest generation 27-60x85mm Razor HD spotting scopes - it is not compatible with the 65mm and 50 mm Razor HD models.

What our Experts Think

• Excellent balance of performance & portability (15–45x65)
  The 15–45x zoom range paired with a 65mm objective delivers strong mid-to-long range performance without excessive size or weight, making it ideal for field use and travel.
• HD optical system with impressive clarity
  Extra-low dispersion (ED) glass, XR coatings, and dielectric prism coatings provide bright, sharp, high-contrast images with accurate color reproduction across the zoom range.
• Reliable low-light performance for its class
  The 65mm objective lens ensures good light gathering at dawn/dusk, though not as strong as larger 80–85mm scopes—still very capable for most real-world scenarios.
• Angled design improves comfort & usability
  45° angled eyepiece allows more comfortable viewing in prone, seated, or standing positions, especially during extended glassing sessions.
• Smooth, precise focusing system
  Helical focus mechanism delivers fast, accurate adjustments without image shift, helping quickly lock onto targets at varying distances.
• Built tough for outdoor conditions
  Magnesium chassis, rubber armor, and argon-filled waterproof/fogproof construction ensure durability in harsh environments.

A: Yes. It includes a standard 1/4"-20 mount and is compatible with Arca-Swiss systems for stable, hands-free viewing.

Q8: How durable is this spotting scope?
A: Built with a lightweight magnesium chassis and rubber armor, it is rugged, shock-resistant, and designed for demanding outdoor use. 

Maintenance Tips

• Clean HD lenses gently: Use a microfiber cloth and lens-safe cleaner only. XR anti-reflective coatings and ED glass require careful handling to maintain brightness and clarity.
• Always use lens covers & sunshade: Protect the objective lens from dust, scratches, and glare—extend the built-in sunshade during use for added protection.
• Avoid touching glass surfaces: Fingerprints reduce light transmission and sharpness, especially at higher magnifications.
• Maintain smooth focus system: The helical focus collar should turn smoothly—avoid forcing it to preserve precise optical alignment.
• Use tripod support: Designed for tripod mounting (Arca-compatible), which ensures stable viewing and reduces strain on internal components.
• Store in dry conditions: Argon-filled and O-ring sealed for waterproof/fogproof use, but long-term moisture exposure can still impact seals.
• Wipe exterior after use: Clean rubber armor and magnesium body to remove dirt, oil, and moisture for long-term durability.
• Rotate collar carefully: The rotating tripod collar allows flexible viewing angles—adjust gently to avoid wear.
• Avoid extreme heat & impacts: Protects coatings, internal alignment, and overall optical performance.
• Use included case for transport: The stay-on case adds protection and allows quick deployment in the field.
